5. SAFETY CHECK BEFORE EVERY RIDE
5.3. HANDLEBAR AND STEM
1. Make sure the handlebar is at a right angle
relative to the front wheel.
2. Place the front wheel between your legs
and try to twist the handlebar. If you can
twist the handlebar, you must tighten the
quick release of the height adjustment. If no
quick release exists, you must immediately
contact your authorized dealer to check the
bolts.
3. Try to twist the handlebar toward the stem
to make sure it does not rotate. If you can
twist the handlebar, you must immediately
contact your authorized dealer to check the
bolts.
4. Check whether the grips as well as the
brake and shift levers are properly secured.
It must not be possible to twist them rela-
tive to the handlebar.
5. Check whether the handlebar can be
turned in both directions without resistance
and without jamming or pinching any of
the hoses or cables.
6. If your bike comes with an adjustable stem,
check whether all pins are engaged and
all quick release levers are properly closed
(see section 7.4. on page 32).
